CHARLES STOOKER, JR, OF SAGINAW, MICHIGAN.

BRIDGE-GATE.

SPECIFICATION forming part of Letters Patent No. 484,122, dated October11, 1892.

Application filed January 20, 1892- Serial No. 418,636. (No model.)

.To all whom it may concern):

Be it known that 1, CHARLES STocKER, J r., a citizen of the UnitedStates, residing at Saginaw, in the county of Saginaw and State ofMichigan, have invented certain new and useful Bridge-Gates; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention is a bridge-gate designed to be simple, sure, and safe andautomatic; and it consists in the arrangement and combination of theparts.

Figure 1 is a front view of the gate and bridge-section. Fig.2 is aviewof the sliding post E and its box H. Fig. 3 is a View of the gate-post,arm, and spring.

In the drawings, A is the pier; B, the bridge; 0 O, the gate-posts atthe side of the driveway and near the draw. G are the gatearms, pivotedto the gate-posts O 0 so as to extend over the driveway and walk whenhorizontal.

D D are the chains or cables connected to the arms near their pivots andextending downward over the pulleys K K at the base ofthe gate-posts andto the pier or base of the bridge.

H is a box or mortise cut into the pier or built at the side just underthe edge of the draw and at the proper distance therefrom. E is a postadapted to fit into the box H, and has upon its top end a roller F,journaled in the top of the post.

To the lower end of the post E is secured the ends of the chain or cableD D. The chains D D may pass down the side of the post E within the boxH, or they may pass down outside the box H part way and connect to thepost through the slots H in the side of the box, as shown in Fig. 2. Itis evident that as the post E is pressed down into the box H the arms ofthe gate will be raised.

S is a coiled spring in the bottom of the box H under the post E, and isintended to push the post up when the pressure on it is removed. Thepost is pressed down by the draw of the bridge as it is swung back intoits place, the shoe R (shown in dotted lines on Fig. 1) passing over theroller F, and, being convex, it gradually forces the post down, andthereby raises the gate. When the draw is swung open, the pressure isremoved from the post E and the arms are lowered by the springs 4,secured on one side of the posts 0 O, as shown in Fig. 3, at one end,the other end secured to the gate-bar G in front of the post 0. Theoperating parts of the gate being below the draw, they are protectedfrom storms, and the other parts being so simple there is nothing to getout of repair, so that my gate possesses the advantage of being simple,cheap, and durable.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

In a bridge-gate, the combination, with the gate, of the cables D D,secured to the arms G G at one end, the other end connected to the lowerend of the sliding post E, and one or more pulleys over which the cablesrun, the sliding post E, the roller F, journaled in the top of the postE, the box H, the coiled spring S within the box H under the post E, theconvex shoe R on the draw, adapted to run upon the roller F, and therebyforce the post E downward, thereby raising the arms, and the springs 4 4for lowering the arms, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
